with t lie thorax. Wings of a uniform snuff-brown, speckled minutely with 

 black, especially along the costa. No basal line on fore wing; a prominenl 

 dusky, diffuse, wavy, extradiscal line, oblique, a little sinuate, parallel with 

 the outer edge of the wing; hall-way between this and the base of the fringe 

 are two indistincl lines, the inner one more distinct and very wavy; a narrow 

 dark line along the base of fringe, which lasl is (dear snuff-brown. A mar- 

 ginal row of distinct, minute, black dots. A faint brown discal dot. The 

 same lines are repeated on hind wings. Beneath, scarcely paler than above, 

 with the extradiscal line black and very distinct, finer than on the upper side; 

 the two other lines very taint, the inner one, however, in some specimens, 

 quite distinct and very wavy. A marginal row of small black dots; the base 

 of both wings is thickly speckled with black scales. 



Length of body, 0.35; fore wing, 0.35-0.46; expanse of wings, 1.00- 

 40 inch. 



Mendocino City, Cal. ; San Mateo, Cal. (A. Agassiz) ; Sanzalito, Cal., 

 May 6 (Behrens); California (Edwards); mountains of Colorado, July 22 to 

 August 29 (Lieutenant Carpenter) ; banks of Blue River, Middle Park, 

 elevation from 9,000 to 10,000 feet (Mead); Colorado (Mr. Ridings). 



Having received more specimens from Mr. Edwards, I find that A. 

 jinrijicaiia is simply a variety of californiaria, differing in its smaller size, 

 the more rounded apex of the fore wings, and the less oblique outer border. 

 The extradiscal line is blacker than usual and much less oblique, with a bend 

 inward below the median vein. Discal dot distinct, black. Near the outer 

 edge is a pale, clear, irregular, scalloped line parallel to the outer edge, and 

 diminishing in width toward the costa. It is as common apparently in Cali- 

 fornia as its representative, A. inductata, is in the States east of the Rocky 

 Mountains.

 much as in .1. rubrolineata ; body rather more hairy than in the Californian 

 species. Dark reddish brick-brown; body and base of wings darker than the 

 wings. Fore win^s rather narrow, with four blackish Hues, the basal farther 

 from the insertion of the wing than usual, and united with the second line on
